【问题描述】：

我想做一个交叉编译 nodejs C++ 插件（node-gyp）。
环境设置如

export AR=/2nd-hdd/home/pkang/sdk/tm2sdk/sysroots/x86_64-oesdk-linux/usr/bin/arm-oe-linux-gnueabi/arm-oe-linux-gnueabi-ar
export CC=/2nd-hdd/home/pkang/sdk/tm2sdk/sysroots/x86_64-oesdk-linux/usr/bin/arm-oe-linux-gnueabi/arm-oe-linux-gnueabi-gcc 
export CXX=/2nd-hdd/home/pkang/sdk/tm2sdk/sysroots/x86_64-oesdk-linux/usr/bin/arm-oe-linux-gnueabi/arm-oe-linux-gnueabi-g++
export LINK=/2nd-hdd/home/pkang/sdk/tm2sdk/sysroots/x86_64-oesdk-linux/usr/bin/arm-oe-linux-gnueabi/arm-oe-linux-gnueabi-g++

这是我的 binding.gyp

{
  'targets': [
    {
      'target_name': 'binding',
      'sources': [ 'binding.cc' ],
      'includes': ['../common.gypi'],
      "cflags" : ['-march=armv7-a -mfloat-abi=softfp -mfpu=neon --sysroot=/2nd-hdd/home/pkang/sdk/tm2sdk/sysroots/armv7a-vfp-neon-oe-linux-gnueabi'],
    }
  ]
}

命令是'node-gyp --arch=arm configure build' 我认为编译已经通过，但链接器显示这样的错误。

有人有类似的问题吗？

【解决方案1】：

我自己解决了这个问题。
这是整个 binding.gyp 文件。

{
  'targets': [
    {
      'target_name': 'binding',
      'sources': [ 'binding.cc' ],
      'includes': ['../common.gypi'],
      "cflags" : ['-march=armv7-a -mfloat-abi=softfp -mfpu=neon --sysroot=/2nd-hdd/home/pkang/sdk/tm2sdk/sysroots/armv7a-vfp-neon-oe-linux-gnueabi'],
      'link_settings': {"libraries": [ "-march=armv7-a -mfloat-abi=softfp -mfpu=neon --sysroot=/2nd-hdd/home/pkang/sdk/tm2sdk/sysroots/armv7a-vfp-neon-oe-linux-gnueabi"], },
    }
  ]
}
